I run one on my HV 4.5 in a hyper 10sc geared for 40mph...I ran 6 2s 30C 5200mah packs through it back to back to back etc etc...and the hottest thin on the car was the lipo at 110....the mmp was 120ish...the 4.5 was consistently 110 but 120 aroung the solder tabs...so the shroud is doing it's job IMHO ....before the shroud I would have to gear down on the motor BC 40mph gearing made the motor 155 consistently (pre-shroud)
